In Response To: Question on visibility in space. (Postmortem) : But what about beyond that? Does the way : visibility works in space allow you to see crystal clear for light years, : or would the curvature of Trevelyan fade out into the blackness much as : mountains fade into grey/white as you get further from them, so that you : could never actually see an abrupt end to it? Mountains fade into grey/white because there's crap in the atmosphere between you and them. Without substantial amounts of gas and junk in between, you'll be able to see it crisp and clear (well, as long as there's enough external light reflecting off of it. Otherwise it could wind up looking like a black round hole in the star field behind it). Distance would only make it hard to see if you got so far away that it no longer swept out much of your FoV. Now, this thing is about 3*10^11 meters across. Which means that at 3*10^13 meters, it would still look a tad bigger in the sky than the moon does from Earth. 3*10^13 meters is ~200AU, 100 times the diameter of the object, .003 light years, or 160% the distance between Earth and Voyager 1. (I hope I did my math right...) : I can imagine it would look quite clear if viewed through a telescope As long as the object is close enough to see it big in your vision, a telescope wouldn't matter much. The eye is capable of focusing to cleanly view objects at infinite distance. The telescope will only be required if you're so far away that the object is tiny in your view.
